SNAP-FASTENER.

Specification of Letters Patent.

Patented Dec. 23, 1920.

Application filed May 1, 1920. Serial No. 378,051.

To all whom it may concern Be it known that I, JOSEPH J. BERNIER, a citizen of the United States, residing at Chartley, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Snap-Fasteners, of which the following is a specification.

My invention relates to snap fasteners adapted for retaining or suspending papers,

watches, or any other articles adapted for engagement or suspension.

The essential objects of my invention are inexpensiveness and facility of manufacture; facility of operation; strength; and security.

My invention consists in the means and mechanism for producing the results above specified which fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification Figure 1 is a plan of a blank from which my fastener is formed,

Fig. 2, a front elevation of the fastener in closed position,

Figs. 3 and 4:, side elevations of the same in closed and open positions respectively,

Fig. 5, a plan view of the same open, and

Fig. 6, a section on line 66 of Fig. 3.

Like reference characters indicate like parts throughout the views.

In constructing the fastener a blank is initially cut from a thin sheet of resilient material as shown in Fig. 1. This comprises an oblong flat body consisting of two parts 9 and 10 with an intermediate portion 11 preferably of retracted width. Upon the portion 9 are oppositely disposed lateral lugs 12 terminating in fingers 13 having circular extremities 14 bent up into hemispherical hollow heads by suitable tools during or after the cutting operation. Near its end centrally thereof the portion 10 is provided with an opening 16 surrounded preferably by a marginal inbent flange concavity or seat 1?. In this case a perforation 19 is cut in the upper portion of the part 9.

The blank is bent into final form by lapping the lugs or arms 12 inwardly against the face of the arm 9, and the fingers are bent into a position and spaced at substantially right angles to the arm and are in substantial alinement with the opening 16 in the resilient arm 10 which is normally preferably inclined relatively to the arm 9.

The diameter of the opening 16 is ample to permit the passage of the members 14 under compression which is permitted by the resiliency of fingers 13. After passage, themembers 14 spring apart into normal posltion making their diameter greater than the diameter of the opening 16, and when a flange 17 is present the rear of the members 14: rest in the seat formed thereby.

Any article such as a watch ring may be passed over the arm 10 and depend from the bend or loop 11 after the parts have been sna ed together, or papers may be impaled on the fingers, and may be held thereby after the snapping operation. A suspension ring may be employed in the perforation 19.

I claim 1. In a snap fastener, two arms, a loop integral with the ends of the arms, spaced compressible fingers carried by one arm, and heads upon the fingers, the other arm being provided with an opening adapted to admit passage therethrough of the heads when the fingers are compressed, the said heads form ing an interlocking engagement with the walls of said opening.

2. In a snap fastener, a fiat arm, a flat vibratory arm integrally connected with the first arm, inwardly folded lateral ears upon the face of the first arm, compressible resllient fingers on the free ends of the ears, and heads upon the fingers, the vibratory arm being provided with an opening adapted to admit the heads therethrough when the vibratory arm is pressed toward the first arm, the said heads forming an interlocking engagement with the walls of said opening.

3. In a snap fastener, two flat arms, a loop integral with the ends of the arms, spaced resilient fingers carried by one arm, curved heads on the fingers, and an annular seat in the other arm provided with a circular opening, said opening being adapted to allow the passage of the heads to the seat when the second arm is pressed toward the first arm, the said heads forming an interlocking engagement with the walls of said opening.

4. In a snap fastener, two arms, a resilient loop connecting the ends of the arms, spaced compressible fingers carried by one arm, and hollow heads upon the fingers, the other arm being provided with an opening adapted to with lateral lugs with fingers opposed to receive the heads when the fingers and arms each other, said fingers and lugs being oomare,compressed, the said heads forming an pressible as they are forced through said interlocking engagement with the walls of opening and interlocked with the walls 01":
